Specification of Letters Patent.

Patented Nov. 21, 191a.

Application filed April 26, 1915. Serial No. 23,943.

To all whom it may concern:

Be it known that we, LAFAYETTE PALME and ABRAM L. TAYLOR, citizens of the United States, residing at Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented new and useful Improvements in Hose-Clamps, of which the following is a This invention relates to certain novel and useful improvements in hose clamps and has particular application to a two-part hose clamp. I

In carrying out the present invention, it is our purpose to provide a two-part hose clamp wherein the. meeting extremities of the sections of the clamp, on the inner surface .of such clamp, will be overlapped by tongues formed integral with one of the sections and acting to prevent mutilation of the hose in the application of the clamp, and in which the sections of the'clamp may be readily and quickly assembled in clamp formation about the hose and detached from each other when occasion demands.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter set forth in, and falling within the scope of, the claims.

In the accompanying drawing; Figure 1 is a cross sectional view through a hose showing our improved clamp applied thereto. Fig. 2 is a collective view showing the parts of the clamp in perspective. Fig. 3 is a longitudinal sectional view through the clamp.

Referring now to the drawing in detail,

1 designates our improved hose clamp as an. entirety, such clamp embodying COIIIPSJIIOH semicircular sections 2 and 3 formed of metal. In the present instance, the section 2 is cut out longitudinally as at 4 and formed on one end of the section 2 and projecting laterally therefrom is a lug 5, while formed on the remaining end of the section 2 and projecting laterally therefrom is an ear 6. Formed on one end of the section-3 and projecting outwardly therefrom at an angle thereto is an ear 7 designed to receive the lug 5 on the section 2 whereby a pivotal connection between the sections 2 and 3 is formed, and formed on the remaining end of the section 3 and projecting laterally therefrom is an ear 8 cooperating with the ear 6 and through these alining cars is passed a securing bolt 9 whereby the sections may be clamped about the hose and held thereon in clamp formation.

In accordance with our invention, the section 3, adjacent to the ear '7, is stamped to form a tongue 10 and this tongue is bent back upon the inner surface of the section 1 and overlies the connection formed by the lug 5 and the ear 7 and extends into the cut out portion 450i the section 2 and forms, in efiect, a continuation of the inner surface of the section 3. Likewise, the section. 3 adjacent to the ear 8 is stamped to form a tongue 11 and this tongue 11 is bent back" upon the inner surface of the section 3 andforms, in effect, a continuation of the inner surface of the section 3 and overlies the space at the point of contact of the ears 6 and 8. These tongues 10 and 11 engage the hose at diametrically opposite points, as clearly illustrated in Fig. 1, and so prevent pinching of the hose. 7

To apply the clamp to the hose, it is only necessary to separate the sections and place the lug 5 in the ear 7. The ears 6 and 8 are now drawn together hy means of the bolt 9, thereby clamping the sections 2 and 3 being applied to the hose or removed there-.

from.

We claim:

. Ahose clamp comprising companion semicircular sections,'a lug formed on one end of one of said sections and projecting outwardly therefrom, an ear formed on the corresponding end. of the other section and adapted toreceive said lug to form a pivotal connection between said sections, ears formed on the remaining ends of said sections and projecting outwardly therefrom, a bolt passed through said ears and adapted to draw said sections together around the hose, one of said sections being stamped adjacent to one end thereof to form a tongue bent back upon such section and overlying the meeting endsof the sections and forming, in eifect, a continuation of the inner surfaces of the sections, said section adjacent to the other end being stamped to form a tongue and the lest-mentioned tongue be- In testimony whefeof We affix our signaing bent back upon the inner surface of the tures in presence of two Witnesses. v section and forming in effect a continuai s tion of the inner surfaces of said sections 4 and spanning the space between the pivoted ends of said' sections said tongues acting to Witnesses:

prevent pinching of the hose at the meet- Row. G. WVARREN, ing ends of the sections of saidvelamp. J. H. Koons.
